durvalumab and eribulin in her2-negative metastatic breast cancer and recurrent ovarian cancer

Conditions: HER2-Negative Metastatic Breast Cancer; Recurrent Ovarian Cancer

Summary: this study will evaluate the recommended phase 2 combination dose (rp2d) of eribulin with durvalumab.

study summary study duration: accrual will take place over the course of 16 months. patients will be treated until unacceptable toxicity or disease progression (expected on average for 6 months) and then followed for one year thereafter. objectives: phase i: to determine the the recommended phase ii dose of eribulin in combination with durvalumab this study will evaluate the recommended phase 2 combination dose (rp2d) of eribulin with durvalumab. if two or more out of 6 patients experience a dose limiting toxicity (dlt) at dose level i or ii, the dose level below that level will be considered the rp2d. if all 3 patients enter dose level-i and experience dlt, the study will be terminated. if the highest level has been reached and \< 33% of patients have experienced dlt, that will be considered the rp2d.
